Look at it this way mate, if you don't have a bill switch in your routines, if you want one - buy prophet. If you usually don't or feel comfortable with bill switches, don't get it.
If you need a good TNR effect, get TNR! unless you don't really like them etc.
They're all awesome, that's why T11 sells em.
The trick that will be the best for you is the one you watch the most and go "wow, I can't wait to show someone that." the one that has the strongest effect on you to see is the one you'll love the most and do the best.
my two cents......
